　本発明は、ボクサーパンツ型使い捨ておむつに関する。 The present invention relates to a boxer pants-type disposable diaper.
　従来より知られている使い捨ておむつのタイプは、テープ型とパンツ型との２種類に大別することができる。テープ型使い捨ておむつは、前身頃又は後身頃のサイドに設置されたテープによって前身頃と後身頃とを相互に連結することで、装着者の胴周りを被覆する胴周り部が形成される。そして、これと共に、ウエスト開口部と一対の脚周り開口部とが形成される構造となっている（例えば下記特許文献１）。 Conventionally known disposable diaper types can be broadly classified into two types: tape type and pant type. In the tape-type disposable diaper, a waist portion covering the waist of the wearer is formed by mutually connecting the front body and the back body with a tape installed on the side of the front body or the back body. Along with this, a waist opening and a pair of leg openings are formed (for example, Patent Document 1 below).
　この一方、パンツ型使い捨ておむつは、前身頃及び後身頃のサイドが、ホットメルトなどによって予め相互に接合されており、テープ式使い捨ておむつのように組み立てることなくパンツの体を成す構造となっている（例えば下記特許文献２）。 On the other hand, the pants-type disposable diaper has a structure in which the sides of the front body and the back body are joined together in advance by hot melt or the like, forming the body of the pants without being assembled like a tape-type disposable diaper. (For example, the following patent document 2).
　パンツ型使い捨ておむつのタイプとしては、下記特許文献２に示されるような、脚の付け根に沿うように、股間下側から腰側脇部にかけてＶ字状に脚周り縁が形成されたブリーフ型や、下記特許文献３に示されるような、脚周りを被覆する脚周り筒部が脚周り縁から延出するボクサーパンツ型などがあった。
　この中でも、ボクサーパンツ型の使い捨ておむつは、脚周り筒部が配置されていることによって、脚周り開口部から排泄物が漏れにくいという利点を有している他、近年見られる意匠の好みの多様化に伴って、需要が高まっている。 As a type of the pants-type disposable diaper, as shown in Patent Document 2 below, a brief type in which a leg periphery edge is formed in a V shape from the lower crotch side to the waist side side part along the base of the leg. As shown in Patent Document 3 below, there is a boxer underpants type in which a leg-periphery cylinder portion covering the leg circumference extends from the leg circumference edge.
Among these, the boxer underpants type disposable diaper has the advantage that the excrement is less likely to leak from the opening around the leg due to the arrangement of the cylindrical part around the leg, and a variety of design preferences recently seen. Demand is increasing along with the trend.

　しかし、従来品では、脚周り筒部の長さが固定寸法であったため、装着者によっては、脚周り筒部が装着者の脚に対してフィットしないことがあった。このような問題を解決すべく、１つの胴周りのサイズに対して、脚周り筒部の長さが違うものを複数用意することも考え得るが、生産性が良くないため、好ましくない。
　そこで、本発明の主たる課題は、脚周り筒部の長さを容易に変更可能であるボクサーパンツ型使い捨ておむつを提供することにある。 However, in the conventional product, the length of the leg-surrounding cylinder part is a fixed dimension, so that depending on the wearer, the leg-surrounding cylinder part may not fit the wearer's leg. In order to solve such a problem, it may be possible to prepare a plurality of leg portions with different lengths for the size of one waist, but this is not preferable because the productivity is not good.
Then, the main subject of this invention is providing the boxer underpants type disposable diaper which can change the length of a leg circumference cylinder part easily.
　次に、上記課題を解決するための手段とそれらの作用効果を示す。

〔第１実施形態〕
　本発明の第１実施形態を、図１及び図２を参照しつつ説明する。
　第１実施形態に係るパンツ型使い捨ておむつ１は、図１及び図２に示されるように、外装体１と、この外装体１内面に固定された内装体３とから主に構成されている。
　そして、外装体１は、装着時において装着者の腹側を被覆する前身頃である前身頃シート１１と、装着時において装着者の背側を被覆する後身頃である後身頃シート１２とで構成されている。なお、前身頃シート１１及び後身頃シート１２の上下方向長さＬ１は、１５０～５００ｍｍとされている。 Next, embodiments of the present invention will be described with reference to the accompanying drawings. In the figure, an arrow H indicates a horizontal direction, an arrow U indicates an upward direction, and an arrow D indicates a downward direction. These are merely determined for convenience in describing the embodiment of the present invention.
[First Embodiment]
A first embodiment of the present invention will be described with reference to FIGS. 1 and 2.
As shown in FIGS. 1 and 2, the pant-type disposable diaper 1 according to the first embodiment is mainly composed of an exterior body 1 and an interior body 3 fixed to the inner surface of the exterior body 1.
And the exterior body 1 is comprised with the front body sheet | seat 11 which is the front body which coat | covers a wearer's abdominal side at the time of mounting | wearing, and the back body sheet | seat 12 which is the back body which covers the wearer's back side at the time of mounting | wearing. Has been. The vertical length L1 of the front body sheet 11 and the back body sheet 12 is 150 to 500 mm.
　図１に示すように、前身頃シート１１及び後身頃シート１２は、コ字状の形状を成しており、それぞれ股間位置１００で凹状に切り欠かれて凹欠部１５を有している。凹欠部１５の形状としては、アーチ状、三角状、台形状等、四角状など適宜の形状が採用でき、好適にはアーチ状、特に図示例のように放物線状が適する。 As shown in FIG. 1, the front body sheet 11 and the back body sheet 12 have a U-shape, and are each notched into a concave shape at a crotch position 100 and have a recessed portion 15. As the shape of the recessed portion 15, an appropriate shape such as an arch shape, a triangular shape, a trapezoidal shape, or the like can be adopted, and an arch shape, preferably a parabolic shape as in the illustrated example, is suitable.
　前身頃シート１１と後身頃シート１２とは、それぞれの両側部に位置する両側部接合部２１と、それぞれの凹欠部１５縁に位置する股間位置接合部２２とで相互に接合されている。前身頃シート１１と後身頃シート１２とがこのように接合されていることによって、外装体１０は、ウエスト開口部ＷＯを有する胴周り部１６と、脚周り開口部ＬＯを有する一対の脚周り筒部１７とを形成している。なお、ウエスト開口部ＷＯの周回り長さは、２００～２０００ｍｍとされており、脚周り開口部ＬＯの周回り長さは１００～１０００ｍｍとされている。また、凹欠部１５の最上部と脚周り開口部ＬＯとの上下方向の離間距離Ｌ２は、５０～２００ｍｍとされている。 The front body sheet 11 and the back body sheet 12 are joined to each other by both side joints 21 located on both sides and a crotch position joint 22 located on the edge of each recess 15. By joining the front body sheet 11 and the back body sheet 12 in this way, the exterior body 10 has a pair of leg cylinders having a waist part 16 having a waist opening WO and a leg part opening LO. Part 17 is formed. The circumferential length of the waist opening WO is 200 to 2000 mm, and the circumferential length of the leg opening LO is 100 to 1000 mm. Further, the vertical distance L2 between the uppermost portion of the recessed portion 15 and the leg opening LO is 50 to 200 mm.
　図２に示すように、前身頃シート１１及び後身頃シート１２は、両者ともに上層不織布１０Ａ及び下層不織布１０Ｂからなる不織布のシートから形成されている。不織布の種類は特に限定されず、素材繊維としては、たとえばポリエチレンまたはポリプロピレン等のオレフィン系、ポリエステル系、ポリアミド系等の合成繊維の他、レーヨンやキュプラ等の再生繊維、綿等の天然繊維を用いることができ、加工法としてはスパンレース法、スパンボンド法、サーマルボンド法、エアスルー法、ニードルパンチ法等を用いることができる。ただし、肌触り及び強度を両立できる点でＳＭＳ不織布やＳＭＭＳ不織布等の積層不織布が好適である。不織布は一枚で使用する他、複数枚重ねて使用することもできる。後者の場合、不織布相互をホットメルト接着剤等により接着するのが好ましい。 As shown in FIG. 2, the front body sheet 11 and the back body sheet 12 are both formed from a nonwoven fabric sheet composed of the upper nonwoven fabric 10A and the lower nonwoven fabric 10B. The type of the nonwoven fabric is not particularly limited, and as the material fiber, for example, synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester or polyamide, recycled fibers such as rayon or cupra, and natural fibers such as cotton are used. As a processing method, a spunlace method, a spunbond method, a thermal bond method, an air-through method, a needle punch method, or the like can be used. However, laminated nonwoven fabrics such as SMS nonwoven fabrics and SMMS nonwoven fabrics are preferred in that both the touch and strength can be achieved. In addition to using a single nonwoven fabric, a plurality of nonwoven fabrics can be used. In the latter case, the nonwoven fabrics are preferably bonded to each other with a hot melt adhesive or the like.
　外装体１０の表面には、不透液性のシートを積層しても良い。この不透液性のシートとしては、ポリエチレン、ポリプロピレン等の少なくとも遮水性を有するシート材を用いることができる。また、この他に防水フィルムを介在して実質的に不透液性を確保した上で不織布シートなどを用いることができる。近年はムレ防止の観点から透湿性を有するものが好適に用いられる傾向にある。この遮水・透湿性シート材としては、ポリエチレンやポリプロピレン等のオレフィン系樹脂中に無機充填剤を溶融混練してシートを成形した後、一軸または二軸方向に延伸することにより得られる微多孔性シートが好適に用いられる。 A liquid-impermeable sheet may be laminated on the surface of the outer package 10. As the liquid-impervious sheet, a sheet material having at least water shielding properties such as polyethylene and polypropylene can be used. In addition to this, a non-woven sheet or the like can be used after substantially ensuring liquid impermeability by interposing a waterproof film. In recent years, those having moisture permeability tend to be suitably used from the viewpoint of preventing stuffiness. The water- and moisture-permeable sheet material is a microporous material obtained by melting and kneading an inorganic filler in an olefin-based resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. A sheet is preferably used.
　図１及び図２に示すように、外装体１０の内面側には、前身頃シート１１側から後身頃シート１２側に連続的に至るように内装体３が配置されている。この内装体３としては、透液性トップシート３１と、不透液性バックシート３２との間に吸収コア３３が配されたた既知の層構造のものを用いうる。 As shown in FIGS. 1 and 2, the inner body 3 is arranged on the inner surface side of the outer body 10 so as to continuously reach from the front body sheet 11 side to the rear body sheet 12 side. As the interior body 3, a known layered structure in which an absorbent core 33 is disposed between a liquid-permeable top sheet 31 and a liquid-impermeable back sheet 32 can be used.
　吸収コア３３の表面側（肌当接面側）を覆う透液性トップシート３１としては、有孔または無孔の不織布や多孔性プラスチックシートなどが好適に用いられる。不織布を構成する素材繊維は、ポリエチレンまたはポリプロピレン等のオレフィン系、ポリエステル系、ポリアミド系等の合成繊維の他、レーヨンやキュプラ等の再生繊維、綿等の天然繊維とすることができ、スパンレース法、スパンボンド法、サーマルボンド法、メルトブローン法、ニードルパンチ法等の適宜の加工法によって得られた不織布を用いることができる。これらの加工法の内、スパンレース法は柔軟性、ドレープ性に富む点で優れ、サーマルボンド法は嵩高でソフトである点で優れている。透液性表面シート３１に多数の透孔を形成した場合には、尿などが速やかに吸収されるようになり、ドライタッチ性に優れたものとなる。 As the liquid-permeable top sheet 31 covering the surface side (skin contact surface side) of the absorbent core 33, a porous or non-porous nonwoven fabric, a porous plastic sheet, or the like is preferably used. The material fibers that make up the nonwoven fabric can be synthetic fibers such as olefins such as polyethylene or polypropylene, polyesters, and polyamides, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in terms of flexibility and drapeability, and the thermal bond method is excellent in terms of being bulky and soft. When a large number of through holes are formed in the liquid-permeable surface sheet 31, urine and the like are quickly absorbed, and the dry touch property is excellent.
　前記吸収コア３３の裏面側（非肌当接面側）を覆う不透液性バックシート３２としては、ポリエチレンまたはポリプロピレンなどの不透液性プラスチックシートが用いられるが、近年はムレ防止の点から透湿性を有するものが好適に用いられる。この遮水・透湿性シートは、たとえばポリエチレンやポリプロピレン等のオレフィン樹脂中に無機充填材を溶融混練してシートを形成した後、一軸または二軸方向に延伸することにより得られる微多孔性シートであり、仮にシート厚が同じであれば無孔シートよりも剛性が低下するため、柔軟性の点で勝るものとなる。 As the liquid-impervious back sheet 32 covering the back side (non-skin contact surface side) of the absorbent core 33, a liquid-impervious plastic sheet such as polyethylene or polypropylene is used. Those having moisture permeability are preferably used. This water-impervious / breathable sheet is a microporous sheet obtained by, for example, melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. If the sheet thickness is the same, the rigidity is lower than that of the non-porous sheet, which is superior in terms of flexibility.
　吸収コア３３としては、積繊パルプ、不織布などの繊維内に吸収性ポリマーを散在させ、クレープ紙、不織布シート、孔開きシート等の透液性シートによって包皮したものが用いられる。ここで用いられる吸収性ポリマーとしては、カルボキシメチルセルロース、ポリアクリル酸およびその塩類、アクリル酸塩重合体架橋物、澱粉－アクリル酸グラフト共重合体、澱粉－アクリロニトリルグラフト共重合体の加水分解物、ポリオキシエチレン架橋物、カルボキシメチルセルロース架橋物、ポリエチレンオキサイド、ポリアクリルアミド等の水膨欄性ポリマーを部分架橋したもの、あるいはイソブチレンとマレイン酸との共重合体等が好適に用いられる。製品の吸湿によるブロッキング性を抑制するためにブロッキング防止剤が添加されたものも用いることができる。また高吸収性ポリマーとしては、粉体状、粒子状、顆粒状、ペレット状、ゾル状、サスペンジョン状、ゲル状、フィルム状、不織布状等のさまざまな形態をもったものがあるが、これらはいずれも本発明において使用可能であり、特に粒子状のものが好適に使用される。 As the absorbent core 33, an absorbent core, a nonwoven fabric or the like in which an absorbent polymer is dispersed and encased with a permeable sheet such as a crepe paper, a nonwoven fabric sheet or a perforated sheet is used. Absorbable polymers used herein include carboxymethylcellulose, polyacrylic acid and its salts, crosslinked acrylate polymer, starch-acrylic acid graft copolymer, hydrolyzate of starch-acrylonitrile graft copolymer, poly A cross-linked polymer such as oxyethylene cross-linked product, carboxymethyl cellulose cross-linked product, polyethylene oxide, polyacrylamide or the like, or a copolymer of isobutylene and maleic acid is preferably used. What added the blocking inhibitor in order to suppress the blocking property by moisture absorption of a product can also be used. In addition, the superabsorbent polymer has various forms such as powder, particles, granules, pellets, sol, suspension, gel, film, and nonwoven fabric. Any of them can be used in the present invention, and a particulate material is particularly preferably used.
　図１及び図２に示すように、前身頃シート１１及び後身頃シート１２のウエスト開口部ＷＯ近傍には、ウエスト部弾性伸縮部材２４、２４…が伸張状態で固定されている。また、前身頃シート１１及び後身頃シート１２には、ウエスト部弾性伸縮部材２４、２４…と上下方向に間隔を開けて胴回り弾性伸縮部材２５、２５…が、伸張状態で固定されている。ウエスト部弾性伸縮部材２４、２４…及び胴回り弾性伸縮部材２５、２５…は、両者ともに水平方向に沿って、且つ上層不織布１０Ａ及び下層不織布１０Ｂの間に配置されている。このようにウエスト部弾性伸縮部材２４、２４…及び胴回り弾性伸縮部材２５、２５…が設けられていることによって、胴周り部１６には、水平方向に対しての伸縮性が付与されている。 As shown in FIGS. 1 and 2, waist elastic elastic members 24, 24... Are fixed in the stretched state in the vicinity of the waist opening WO of the front body sheet 11 and the back body sheet 12. Further, waist elastic elastic members 24, 24...
